Senior Unity Developer Needed – 3D Sci-Fi Endless Runner (Long-Term Project) Project Overview We’re seeking an experienced Unity developer to build a premium-quality 3D sci-fi endless runner for PC (Steam) and iOS. The project is divided into multiple milestones, with each milestone delivering a complete, playable version of the game along with the full Unity source project and C# source code. This is a long-term project focused on creating a scalable architecture that can support years of future content updates. The successful developer will receive priority for all future milestones. Tech Stack * Unity (Latest LTS) * C# * URP * Windows / Steam * iOS * Architecture ready for future Android support Core Gameplay Players pilot a futuristic UFO through an endless cyberpunk world, avoiding obstacles, defeating enemies with cooldown-based abilities, collecting currency, completing objectives, and progressing through increasingly difficult stages. Gameplay Loop: Fly → Dodge → Fight → Collect → Upgrade → Reach Portal → Boss Battle → Next Stage → Repeat Core Systems * Infinite procedural level generation * Dynamic difficulty scaling * Stage progression * Unique boss encounters * Skill system * RPG progression * Save system * Currency & upgrades * Unlockable UFOs & cosmetics * Missions & achievements * Expandable content framework Technical Requirements * Production-quality C# * Modular architecture * ScriptableObject-driven systems * Event-driven design * Object Pooling * Addressables * Optimized for PC & mobile * Stable 60 FPS * Clean, documented code * Easy to expand without major refactoring Deliverables (Per Milestone) Each completed milestone must include: * Fully playable game build * Complete Unity project * Full C# source code * Organized project structure * Documentation * Prefabs & scenes * Any systems completed during that milestone * Ownership transferred upon payment Milestone Structure The project is intentionally divided into multiple milestones. Each milestone represents a functional game update rather than isolated features. Examples include: * Core gameplay foundation * Procedural generation * Combat & enemy systems * Boss framework * Progression & upgrades * UI & player systems * Polish & optimization * Final release preparation Every milestone must remain fully playable and buildable. Ideal Freelancer Looking for someone with experience in: * Unity & C# * Procedural generation * Endless runners or roguelites * Mobile optimization * Steam deployment * iOS deployment * Object Pooling * Addressables * Software architecture * Building scalable, maintainable game systems Please include examples of previous Unity gameplay programming or shipped titles. Long-Term Opportunity This is the first phase of a much larger game.

Hi, This project needs more than an endless runner prototype; it needs a core architecture that can scale for future stages, bosses, UFOs, upgrades, and platform expansion without rewrites. I’d start with a clean Unity C# foundation for the core loop: fly, dodge, fight, collect, and progress, then build procedural generation, difficulty scaling, and stage transitions on top. I develop modular Unity systems using ScriptableObjects, event-driven flow, object pooling, and Addressables, with performance in mind for PC and iOS. My first priority would be a stable playable base: movement, obstacles, enemy/spawn logic, currency, basic upgrade/save flow, and a milestone-ready project structure that is easy to extend. Initial focus: Core UFO controller Endless track/procedural spawning Enemy and ability framework Save/currency progression Build-safe project structure Timeline: I can begin immediately and deliver the first playable milestone quickly, with a structure designed for efficient future expansion. One quick question: do you want each milestone as a separate playable build with its own source handoff, or a single growing project with milestone branches/versions?

Hi there! I saw your project about creating a sci-fi endless runner and immediately thought about how tricky it can be to balance fun gameplay with smooth performance on both PC and iOS. Sometimes, making the game scalable while keeping the code simple enough for future updates sounds like a real puzzle. To handle your needs, I plan to develop a flexible and modular core architecture similar to the systems I built for an endless runner, where systems are easy to upgrade or swap out. I'll implement features like procedural level creation, optimized object pooling, and a clean save system, ensuring everything is organized with ScriptableObjects and event-driven design that’s both easy to understand and expand. For visual quality, I will utilize URP for vibrant graphics, matching your sci-fi aesthetic, and optimize for 60 FPS on all supported devices. Clear communication, quality work, and timely delivery will help speed up your project and support your long-term vision. Your project jumps from UFO dodging to boss fights, and I wonder—how do you envision balancing difficulty with rewarding progression so players stay engaged without frustration? Let's discuss your plans and brainstorm how we can build something truly impressive together. Regards, Nick
